I've got an A/B Test set up in Adobe Test-and-Target. The idea is that 50% of the time, visitors to a certain page should be redirected to a different page instead. It is working correctly, in that half of users are sent to the new page.
However, sometimes the entire original page is loaded before the redirect happens. I put the mbox in the head tag of the page, which I thought would ensure the redirect happened before any HTML was displayed to the user, but that's not happening.
How can I create a seamless result for the user, where the redirected users only see the new page loading, and never see the original page?
